Yamaha RX-V681

[kamleshbarot]

Hey,

I'm trying to update firmware for my Yamaha RX-V681 but during the S1-6 erasing the display flashes an error 090000 & 010000, alternatively.

Could someone help me how to override this EPROM Flash erase and writing or is some wire loose from the main board that connects this IC86?

don’t think wire loose, firmware update has corrupted or bricked your AVR.

Try to get Yamaha service manual. Troubleshooting will be explained step by step.
